Sioux Chief 642PX3 Pex 90 Degree Elbow 3/4 in Polymer 25pk

Product Description

The SIOUX CHIEF 642PX3 is a 3/4-inch polymer 90-degree elbow fitting designed for PEX tubing systems in residential and light commercial plumbing applications. Made from polymer construction, this elbow provides a reliable directional change in PEX supply lines without the corrosion concerns associated with metal fittings. Sold in bags of 25, the 642PX3 is well suited for plumbers and contractors who need consistent, job-ready quantities for roughing-in water distribution systems. The fitting is sized at 3/4 inch on both ends, making it a straightforward insert-style elbow for standard 3/4-inch PEX tubing runs.

This elbow is used in potable water distribution systems where PEX tubing requires a 90-degree direction change. Typical applications include residential water supply roughing, manifold branch lines, and retrofit plumbing where copper or CPVC is being replaced with PEX. The bag-of-25 packaging makes it practical for new construction and multi-unit projects where volume installation is common. Licensed plumbers and experienced pipefitters are the primary installers of this type of PEX insert fitting.

Key Features

• 3/4-inch by 3/4-inch sizing fits standard PEX tubing on both ends
• 90-degree turn geometry for directional changes in supply line routing
• Polymer construction resists corrosion and scale buildup
• Sold 25 fittings per bag for volume installation efficiency

Compatibility

Designed as an OEM-style insert fitting for use with 3/4-inch PEX-A, PEX-B, and PEX-C tubing in potable water distribution systems using crimp ring or clamp ring installation tools.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and IPC requirements for PEX systems. Shut off the water supply and depressurize the line before cutting into any existing piping. Use a properly calibrated PEX crimp or clamp tool to secure the appropriate ring over the fitting barb — do not over-drive or under-drive the ring. Inspect each connection for full ring seating before pressurizing the system.
